SPECIFICATION forming part of Letters Patent No. 544,274, dated August 6, 1895.

Application filed May 22,-1895. Serial No. 550,227. (No model.)

To all whom it may concern.-

Be it known that LWILLIAM J. FERGUSON, a citizen of the United States, residing at Baltimore, in the State of Maryland, have' invented certain new and useful Improvements in Automatic Oilers, of which the following is a specification.

This invention relates to an improved automatic oiler to be carried on the movable parts of engines and machinery.

The invention will first be described and then specifically pointed out in the appended claims.

In the accompanying drawings, Figure l is a side elevation of the improved oiler. Fig. 2 is a vertical cross-section of the oiler. Fig. 3 is a view of the cap of the interior cup. Fig. 4 is a view of the holder for the absorbent material. Fig. 5 is a top view of the washer. Fig. 6 is a top view of the oil-controlling plate.

The letter A designates the exterior case, which may be of any suitable form, but in the present instance is circular or round. At the bottom is a screw-threaded neck b having a passage c for the discharge of oil. This neck is adapted to engage with a screwthreaded hole in any movable part of an engine or machine.

The case A has a glass or mica side d. On the inner wall of the case is a shoulder e, and the glass panel d rests thereon. The inner edge of the case outside of said shoulder has a screw-thread f, and a ring g screws thereinto and thus contines the glass panel. A suitable washer h h is on either side of the glass or mica panel, and serves to make the parts tight. The glass side shows the amount of oil in the chamber B, and also shows the action of the oil as it is thrown or sloshed from one side to the other. The top of the case has a circular opening and a angefi around it, which is screw-threaded and closed by a screw-cap j. j

An interior cup K has at its bottom a tubular stem Z, which fits in the neck b of the case, and a passage c in this stem connects with the passage o .in the neck. The stem l supports the cup K rigidly. This cup is imperforate, except the open tubular stem at the bottom. Within the cup is an open-work or perforated holder mier suitable absorbent material n, such as cottonwaste or sponge. The top of the holder fm. has a ring o with a lateral flange o', which latter sets upon the vtop edge of the cup K, while the perforated holder m hangs pendent within the cup, and an annular space 19 is formed around the said holder and between it and the wall of the cup. It will be seen that oil may ooze through the perforations of lthe holder at its sides, as well as at the bottom, and the annular space p affords facility for this oozing.

The cap K of the interior cup sets down over the lateral flange o and screws onto the cup. Thus this cap closes the cup, and by pressing on the flange o also contines the pendent holder. The cap has at one side an inlet-hole q and an upward-projecting stem r in the center. At its base this stem is square, and above the square part it is screw-threaded, as at r. A plate s is on top of the cap K', `and has in the center a square hole t, which fits over the square base of the stem r, and is thereby prevented from turning. This plate s has four holes u u? us a4 of graduated size, from u', the smallest in size, to u, the largest. This plate may be set in position on the cap so as ,to have either of the said graduated holes coincident with or in register with the inlet-hole q in the cap. Thus, the particular one of these four holes which happens to be in register with the inlet q will constitute the control of feed-oil, and may be adjusted by changing the holes. A thumb-nut o fits on the screw-threaded 'part fr of the stem and contines the oil-controlling plate s to its position. A suitable washer w is, or may be,`interposed between the top of the cap K and the plate s. This washer is intended to remain stationary and has a hole q", which is in register with the inlet-hole q in the cap.

It will be seen that in operation, when the chamber B contains oil to a point below the cap of the interior cup K, the sloshing of the oil, caused by the constant movement of the entire device, will cause oil to lodge on the plate s and some of this oil will pass through y one of the graduated holes and the inlet-hole q into the holder fm, where it will be absorbed by the material n. The oil held absorbed will IOO then trickle orilter through the material and ooze from the perforated holder and drop down the passage c' c to the part of machinery that is to be oiled.

The tubular stem Z of the interior cup has a small hole which allows oil to How to the passages c c direct from the chamber B without first passing through the cup K or through the absorbent material n. This direct feedhole is governed by a valve y which passes through the exterior case in the wall of which its screw-thread y lits. By turning the arm y2 on the outside this valve will partly' or entirely open the direct feed-hole at, or will entirely close said hole. This direct oil-feed zr, is useful when a crank, eccentric, or other part needs flushing, as when new, or after it has been cleaned or repaired.

The interior cup K may be made integral with the case or as a separate part.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. An automatic oiler comprising an exterior case having at its bottom a neck with a passage in it for discharging oil; an interior cup having apassage which connects with the said discharge passage of the case and said exterior case forming an oil-chamber which surrounds the cup; a perforated holder inside of the interior cup with a surrounding space between the two and said holder containing absorbent material; and a cap closing said interior cup-said cup having an inlet hole.

2. An automatic oiler comprising an eXterior case having at its bottom a neck with a passage in it for discharging oil; an interior cuphaving a passage which connects with the said discharge passage of the case and said 4exterior case forming an oil-chamber which surrounds the cup; a perforated holder inside of the interior cup with a surrounding space between the two said holder being secured by its top and hanging pendent within the cup; a cap closing said cup, and a plate with graduated holes to control the feed of oil into the said cup and holder.

3. An automatic oiler comprising an exterior case having at its bottom a neck with a passage in it for discharging oil; an interior cup having a passage which connects With the said discharge passage of the case and said exterior .case forming an oil-chamber which surrounds the cup; a cap closing said interior cup and having an inlet hole and provided with an upward-projecting stem; and an adjustable plate resting on said cap and provided with a series of holes of graduated size either one of which may register with said hole in the cap.

4. An automatic oiler comprising an eXterior case having at its bottom a neck with a passage in it for discharging oil; an interior cup having a passage which connects with the said discharge passage of the case and said exterior case forming an oil chamber which surrounds the cup; a cap closing said interior cup and having an inlet hole and provided l with an upward-projecting stem having a square base and a screw-threaded end; an adjustable plate resting on said cap and provided with a series of holes of graduated sizes either' one of which may register with said inlet hole in the cap and said plate having a square hole to fit about the said square base; and a screw nut to take on the said stem and retain the adjustable plate in position.

5. An automatic oiler comprising an exterior case having at its bottom a neck with a passage in it for discharging oil; an interior cup having a passage which connects with the said discharge passage of the case and said exterior case forming an oil chamber which surrounds the cup; an oil inlet at the top of the said cup; a feed hole direct from the oil-chamber to the oil-discharge passage below the cup; and a valve to open and close said feed hole,- the stem of said valve passing through the oilchamber and the exterior case to the outer side.

In testimony whereof I aiix my signature in the presence of two witnesses.
